Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a specular wood material. More specifically, the present invention provides a mirror surface coating that has good appearance even with a wood material having a complicated cross-sectional shape due to the presence of grooves and the like, and that can be manufactured efficiently and efficiently by reducing the number of coating steps. It concerns wood materials.

[0002]

2. Description of the Related Art Conventionally, the surface of a wooden material such as a furniture door has often been subjected to a piano-touch mirror surface coating, and various methods have been devised for that purpose. Usually, such a mirror-finished wood material is subjected to polishing and buffing (e.g., as shown in FIG. 6), in which the surface of a wood base material (a) is sequentially coated with an undercoat (a) and an intermediate coat (c). ) Is performed, and then a top coat (e) is applied, followed by polishing and buffing (f) finishing, and a mirror surface is formed on the surface to manufacture.

Such a mirror-finished wood material of piano touch is
It has been attracting attention as a material that gives an excellent texture and a sense of quality when used for furniture doors.

[0004]

However, as is apparent from FIG. 6, the conventional mirror-finished woody material as described above is undercoated (a), intermediate-coated (c), polished / buffed (d), and top-coated. (E) and polishing / buffing (f) are multi-staged and manufactured by a large number of processes, so that there is a great limitation in improving work efficiency and productivity.

Further, in the case of this conventional manufacturing method, for example, a wood material (a) having a complicated cross-sectional shape due to the presence of a groove (ki) as shown in FIG.
If the groove portion (ki) or the step portion has any shape as illustrated in FIGS. 8 and 9, the inner surface of the groove portion (ki) is subjected to polishing and buffing. It was extremely difficult.

Usually, when polishing / buffing is not performed after the undercoating (a) and the intermediate coating (c), the smoothness of the surface is not obtained and the appearance as a mirror surface is remarkably deteriorated. Up to this point, it is almost impossible to form a mirror surface on a wood material (a) with a complicated cross-section, and if it is attempted to form a mirror surface, it will take a great deal of labor and time to finely finish it by hand, improving productivity. However, there were major restrictions on reducing production costs.

Therefore, in order to solve such a drawback, the inventor of the present invention, as shown in FIG. 10, forms a resin sheet (black) on the surface of a wood material (a) having a groove (ki) formed in advance. ) Was applied, and a top coat coating (K) was applied on the resin sheet (K), and a mirror-finished method was proposed. This method makes it possible to achieve high productivity without compromising the appearance of wood-based materials, even if the wood-based materials have complicated shapes.
Is advantageous in providing.

However, in the subsequent examination, it became clear that the mirror surface forming method by sticking the resin sheet (K) still has a problem to be solved. This is because, in the case of this improved method, the coating of the groove portion, for example, the groove portion (g) at the boundary portion between the frame body and the end plate shown in FIG. This is because it has been found that the cause is the so-called paint sag, which is the flow of paint into the groove (g).

The present invention has been made in view of the circumstances as described above, and even in the case of a wood material having a complicated cross section, which has conventionally been difficult to form a mirror surface, paint sagging to a boundary portion such as a groove portion is also possible. It is an object of the present invention to provide a new mirror-finished wood material capable of efficiently forming a mirror surface without causing non-uniformity of coating between the groove portion and the flat surface portion and greatly impairing its appearance.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a frame body having a central opening, each of which has a resin sheet attached thereto, a top coat coating applied thereon, and a mirror finish. To provide a mirror-finished wood material, characterized in that a frame assembly made of and a mirror plate for closing the opening are assembled and attached.

Further, the present invention has one aspect in which a thick resin sheet is attached to the protruding surface of the end plate and a thin resin sheet is attached to the other surface.
Of course, in the present invention, there is no particular limitation on the type of wood material as the base material, and it is possible to use moku wood, particle board, laminated wood, or any other wood material, and also for the resin sheet. There is no particular limitation, vinyl chloride resin, polyolefin resin, acrylic resin,
As the other resin, an appropriate resin sheet having a relatively hard surface can be used. There is no limitation on the thickness of the sheet. On average, it is possible to use one having a size of about 0.2 to 0.5 mm. However, as described above, it is preferable to use a relatively thick portion, such as 0.5 mm or more, for a portion having a relatively large flat area such as the protruding surface of the end plate to ensure the surface smoothness after the sheet is attached. .. For other parts, the area of the flat surface is small, so even if the flatness of the surface is a little poor due to the characteristics of the wood base material, it is not so much.
It is possible to use a relatively thin resin sheet of less than.

By varying this thickness, a well-balanced finish is possible as a whole. The resin sheet can be easily adhered to the above-mentioned wood base material by means of a vacuum press or the like by using urethane or polyester as an adhesive.

Each top coat of the frame and the end plate after sticking the resin sheet is made of polyester, polyurethane or the like.
For example, it can be done using poly clear paint,
The thickness of the coating film is also arbitrary. Note that a paint mixed with a coloring agent may be used as the top coat. Then, in the present invention, the top-coated surface can be subjected to polishing / buffing. Of course, various finishing mirror surface formation is possible. The frame and the mirror plate as the frame body of the present invention, which are mirror-formed in this way, are then assembled and attached by adopting a structure such as actual coupling.

In the wood material of the present invention as described above, the surface smoothness is secured by sticking the resin sheet to the base material, and finishing treatment such as polishing and buffing after overcoating is carried out in the groove portion or the step portion. Even if it is not applied to the surface, the specularity of the wood material is not significantly impaired. Hereinafter, the present invention will be described in more detail with reference to examples.

[0015]

EXAMPLE A mirror-finished wood material of the present invention, which can be shown in, for example, FIG. 4, was manufactured along the steps shown in FIGS. 1, 2 and 3. That is, as illustrated in FIG. 1, (a) First, for example, a medium density fiber board (MD
Using F), a frame frame base material as a furniture door material (1)
And an end plate base material (2) are prepared.

(B) A vinyl chloride sheet is attached to the surfaces of the frame base material (1) and the end plate base material (2) by vacuum pressing using a urethane adhesive. (C) Next, the surface of each vinyl chloride sheet is top-coated with, for example, a polyester paint. The coating film formed by this top coating is dried and cured. Depending on the type, photocuring treatment may be performed.

(D) After this curing treatment, the coated surface is polished and buffed to form a mirror surface. (E) And finally, the frame-formed frame and the mirror plate are assembled and attached. FIG. 2 shows the steps of FIG. 1 for the end plate. First, the resin sheet (3) is attached onto the end plate base material (2), the finish coating (4) is applied thereon, and after this is dried and cured, it is polished and buffed to form a mirror surface.

FIG. 3 shows an example of the above-mentioned assembly and attachment. In the groove (13) of the frame set (11) with a mirror surface,
Both side edges (14) of the end plate (12) are fitted and assembled and attached. FIG. 4 is a plan view and a sectional view showing the assembled and completed state. In the above steps, as the vinyl chloride resin sheet (3), the end plate base material (2) having a thickness of 0.8 mm and the others having a thickness of 0.3 mm were used. A uniform and excellent-looking furniture door material was produced. The boundary groove (15) after assembling and attaching had no paint dripping, and could be simply manufactured.

Of course, in this step, both the front and back surfaces of the end plate base material (2) may be treated, or only the surface may be finished. As the top coating (4), flow coating, brush coating, roll coating, doctor blade coating, and other appropriate means are adopted, and as polishing / buffing, various ordinary means can be used.

Further, the assembling and mounting is not limited to the above example. For example, as illustrated in FIG. 5, the side edge (14) of the end plate (12) may be brought into contact with and bonded to the step portion (16) of the frame assembly (11) from its back surface.

[0021]

As is apparent from the above steps, the complicated steps such as the groove portion are required without requiring many steps and works which are indispensable in the conventional methods of undercoating, intermediate coating and polishing. Even in a wooden material such as a door having a groove, there is no paint dripping in a groove or the like, and it is possible to efficiently realize a mirror-like wooden material having a uniform smoothness and a uniform mirror surface property and a good appearance.

In fact, in this way, a mirror surface plate as a cabinet door material can be obtained with excellent productivity and quality. Of course, the present invention is not limited to the above examples, and various modes are possible.
